Detailed Description of the Invention Embodiment

[0020] Reference Figures 1 to 4, a dust-proof feeding device described in this embodiment includes a feeding tank 1. A feeding port 2 is provided on one side of the feeding tank 1. A baffle 3 is hinged on the feeding tank 1 on one side of the feeding port 2. One end of the baffle 3 away from the feeding port 2 is fixedly connected with a handle. On the other side of the feeding tank 1 at the feeding port 2, a clamping seat 4 is fixedly connected. A clamping component 5 is provided on one side of the clamping seat 4. The clamping seat 4 is fixedly connected with the baffle 3 through the clamping component 5. The upper end of the feeding tank 1 is fixedly connected with an installation sleeve, and the installation sleeve is communicated with the feeding tank 1.

On one side of the feeding tank 1, a support platform 11 is fixedly connected. The support platform 11 is used to place the feeding box, playing a certain supporting role and facilitating the pouring of the material into the feeding port 2. By setting the feeding tank 1, a feeding port 2 is opened in the middle part of the feeding tank 1. Compared with the traditional funnel-shaped port, baffles are provided around the feeding port 2, and a baffle 3 is hinged at the feeding port 2. Therefore, after the feeding is completed, the material in the feeding tank 1 can be prevented from floating out. The scattered part of the dust is extracted under the action of the exhaust fan 8, avoiding harm to the workers' bodies and polluting the workshop environment, and also reducing the difficulty of cleaning and maintenance.

[0021] Reference Figure 2 , the clamping component 5 includes a slot 51 opened inside the clamping seat 4. A clamping block 52 is movably connected inside the slot 51. The clamping block 52 is of an arc-shaped structure. A groove 54 is opened on one side inside the slot 51. A spring 53 is fixedly connected inside the groove 54. One end of the spring 53 is fixedly connected with one end of the clamping block 52. One side of the baffle 3 is movably connected with the slot 51 and is also movably connected with the clamping block 52. One end of the clamping block 52 is fixedly connected with a guide rod 55. The guide rod 55 is located inside the spring 53. One side of the guide rod 55 is slidably connected with the groove 54. By setting the clamping component 5, when feeding is required, the baffle 3 is driven to move through the handle. At this time, the arc-shaped clamping block 52 is subjected to a thrust force and moves under the action of the spring 53, separating the clamping block 52 from the baffle 3, and the baffle 3 can be quickly opened for feeding. On the contrary, when closing the baffle 3, the baffle 3 enters the slot 51 and is connected with the clamping seat 4. At this time, the clamping block 52 quickly fixes the baffle 3 under the action of the spring 53. It should be noted that round holes are opened on the baffle 3 for matching the clamping block 52.

[0022] Reference Figures 1 - 2 , a positioning block 6 is fixedly connected to the other side inside the slot 51. Positioning grooves 7 are opened on both sides at one end of the baffle 3. The positioning block 6 is movably connected with the positioning grooves 7. By fixedly connecting the positioning block 6 inside the slot 51 and opening the positioning grooves 7 on the top cover, the connection between the baffle 3 and the clamping seat 4 can be made closer.

[0023] Reference Figure 1One end of the mounting sleeve is fixedly connected with a dust exhaust pipe 10, and the dust exhaust pipe 10 is communicated with the mounting sleeve; by providing the dust exhaust pipe 10, the dust in the loading tank 1 can be discharged.

[0024] refer to Figure 3 The cleaning assembly 12 includes a cylinder 124, which is fixedly connected to the inside of the feeding tank 1, and an extension rod 123 is fixedly connected to the output end of the cylinder 124, and a moving ring 121 is fixedly connected to the extension rod 123 away from the output end of the cylinder 124. The upper side of the moving ring 121 is sloped, and a scraping pad 122 is fixedly connected to the outer surface of the moving ring 121. One side of the scraping pad 122 contacts the inner wall of the feeding tank 1, and one end of the extension rod 123 is fixedly connected to a connecting sleeve 125, and the extension rod 123 is fixedly connected to the output end of the cylinder 124 through a locking screw 126; by setting a cleaning When it is necessary to clean the inner wall of the lower half of the feeding tank 1 through which the material passes, the cylinder 124 drives the extension rod 123 to move. The extension rod 123 extends the length of the output shaft of the cylinder 124, so that the extension rod 123 drives the moving ring 121 to move in the feeding tank 1. Under the action of the scraper pad 122, the adhesion of the material is reduced and the waste of raw materials is avoided. Since the upper half of the moving ring 121 is sloped, the material is prevented from accumulating on the moving ring 121. When it is necessary to take out the moving ring 121, the locking screw 126 can be rotated to make it leave the output shaft of the cylinder 124, and the moving ring 121 can be taken out.

[0025] The utility model relates to the following advantages: when feeding, the baffle cover 3 is opened to feed the materials; after the feeding is completed, the baffle cover 3 is quickly closed to connect it with the feeding tank 1 and then quickly fixed by the clamping assembly 5; the materials are transmitted to the next process along the conical outlet below; the raised dust is sucked away by the fan in the fixed installation pipe 9 at the upper conical mouth, which effectively reduces the dust overflow into the workshop environment, greatly reduces the harm and trouble caused by the dust, and improves the environmental protection of the equipment; since the upper part of the moving ring 121 is sloped, the materials are prevented from accumulating on the moving ring 121; when it is necessary to clean the inner wall of the feeding tank 1 where the materials pass, the cylinder 124 drives the extension rod 123 to move, and the extension rod 123 drives the moving ring 121 to move; the contact part between the moving ring 121 and the inner wall of the feeding place of the lower half of the feeding tank 1 is provided with a scraping pad 122, which can scrape off the attached materials and make them fall down and be discharged, so as to avoid the waste of raw materials caused by the attachment of a large amount of materials.
